A two wire DC ring main distributor ABCDEA is fed at point C with 230V supply. The resistances of go and return conductors of each section AB, BC, CD, DE and AE are 0.1 2 each. The main supplies the loads of 20A at A, 10A at B, 10A at D, 30A at E. Estimate: i. voltage at each load point ii. minimum consumer voltage.
